Falzone said one big thing she’s learned over the years is that your attitude and emotions rub off on your employees, which is why it’s so important to maintain composure in front of them.

“I didn’t realize this so much when I started, but everything stems from you,” she says. “If I’m ever stressed, I try to either not show it to my employees, or I go work in my office for a little while.”

When your employees sense your anxiety, it tends to stress them out. And that can hurt productivity and morale.

Luckily, the same philosophy applies to more positive emotions. You should never hide happiness from employees, she says, because when you’re happy, they’re more content, too.
